Hi!

I'm creating a standalone java source code analyzer tool. The tool needs to
have access to the ast node bindings but I can't find a way to make them
available.

What steps are necessary to properly parse a single java source file and get
the resolved bindings?

void analyze(File inputFile) {
ASTParser parser = ASTParser.newParser(AST.JLS2);
parser.setUnitName(inputFile.getName());
parser.setResolveBindings(true);
parser.setSource(readChars(inputFile));

CompilationUnit cu = (CompilationUnit)parser.createAST(null);
// no bindings available!!
// ...
}

Thanks in advance,
Rodrigo

PS: ResourcesPlugin.getWorkspace() returns null as expected since there's no
workspace in scope. I couldn't find a straightforward example of how to
properly initialize a workspace.

I have been asking for the same for some time now, without sucess. I
always get redirected to the JDT tests, but have not been able to parse
the information contained there.

Maybe the people who maintain AST will realize how valuable it could be
if it was made independent of the workbench. It has worked tremendously
well for SWT, and modularity it's always a good goal.

Anyway, please let this list know if you succeed, and how.

Hi Andres,

I solved my problem by creating an plugin that contributes to the
org.eclipse.core.runtime.applications extension point. All I have to provide
to eclipse is a class that implements IPlatformRunnable and then I can take
complete control over the process.

package bamboo.hello;

public class HelloApplication implements IPlatformRunnable {

public Object run(Object arg0) throws Exception {

System.out.println("it worked!");

String[] args = (String[])arg0;
for (int i=0; i<args.length; ++i) {
System.out.println("arg[" + i + "] = " + args[i]);
}
// ResourcesPlugin.getWorkspace() works ok here!
}
}

And then in plugin.xml:

<extension
point="org.eclipse.core.runtime.applications"
id="app"
name="Hello App">

<application>
<run class="bamboo.hello.HelloApplication" />
</application>
</extension>

After the plugin is properly deployed I can start the contributed
application with the following command line (the id of the plugin is
bamboo.hello):

java -cp startup.jar org.eclipse.core.launcher.Main -application
bamboo.hello.app -data "/tmp/workspace" arg1 arg2


This solution works very well for me for all I need is a command line
application. YMMV.

cheers!
Rodrigo
